Wood-plastic composites in the interfacing of two industries PVC profile extrusion line (2)

Wood-thermoset composites date to the early 1900s. An early commercial composite marketed under the trade name Bakelite was composed of phenol-formaldehyde and PVC profile extrusion line. Its first commercial use was reportedly as a gearshift knob for Rolls Royce in 1916 (Gordon 1988). Wood-thermoplastic composites have been manufactured in the United States for several decades, and the industry has experienced tremendous growth in recent years. This article focuses on wood-thermoplastic composites, which are most often simply referred to as wood-plastic composites (WPCs) with the understanding that the plastic is a thermoplastic.
